Level converting circuit for converting level of an input signal, internal potential generating circuit for generating internal potential, internal potential generating unit generating internal potential, highly reliable semiconductor device
摘要：
The level converting circuit includes a first current cutting circuit, a second current cutting circuit, a level shift circuit and an inverter. The first current cutting circuit includes two PMOS transistors connected to a node having a boosted potential Vpp. The second current cutting circuit includes two NMOS transistor connected to a ground node. The level shift circuits include two PMOS transistors and two NMOS transistors. Before a through current flows between the node having the boosted potential Vpp and the ground node, any of the transistor included in the first current cutting circuit and any of the transistors included in the second current cutting circuits are turned off. Therefore, through current between the node having the boosted potential Vbb and the ground node can be prevented.
摘要（中）：

电平转换电路包括第一电流切断电路，第二电流切断电路，电平移位电路和反相器。 第一电流切割电路包括连接到具有升压电位Vpp的节点的两个PMOS晶体管。 第二电流切断电路包括连接到接地节点的两个NMOS晶体管。 电平移位电路包括两个PMOS晶体管和两个NMOS晶体管。 在直流电流在具有升压电位Vpp的节点和接地节点之间流动之前，包括在第一电流切割电路中的任何晶体管和包括在第二电流切割电路中的任何晶体管都被截止。 因此，可以防止具有升压电位Vbb的节点与接地节点之间的电流。
